Morty Smith is one of the two titular main protagonists (alongside Rick Sanchez) of the animated series Rick and Morty, the neurotic and anxious grandson of the mad scientist Rick Sanchez. He is frequently dragged into Rick's dangerous and morally questionable interdimensional adventures, initially as a reluctant sidekick but later developing more confidence and independence. Morty is known for his distinctive appearance, including a yellow shirt, blue pants, and a round head, and is voiced by Justin Roiland in the first six seasons.
